Your unit uses MultiMedia Cards to store information, such as custom
maps, waypoints, trails and other GPS data. The unit can also use Se-
cure Digital Cards (SD card or SDC) to store data. The unit can use up
to two cards; an MMC and an SDC can be used at the same time.

Throughout this manual, we will use the term MMC, but just re-

Both of these solid-state flash memory devices are about the size of a
postage stamp. A SD card is slightly thicker than a MMC. MMCs are
available in storage capacities of 8 MB, 16 MB, 32 MB, 64 MB and
higher. SD cards are available in capacities of 8 MB, 16 MB, 32 MB, 64
MB, 128 MB, 256 MB and 1 GB.
Additional MMC cards are available from LEI Extras; see ordering in-
formation inside the back cover of this manual. MMCs and SD cards
are also available at many camera and consumer electronics stores.
